Cache policy with the Streaming API


Hello there,

I use the streaming API on my website to get last tweets about multiple subjects.
I need to keep the last 5 tweets the stream give me for caching purpose. Those tweets are deleted when the streaming API sent me new tweets (at the end, there is always 5 tweets in my cache).

Can i do that? There is a violation of the Developer Rules of the Road (
Thank you for the answer, sorry for my English.
